CHAIN PUMP.

Specification of Letters Patent No. 16,603, dated February 10, 1857.

To all whom it may concern:

Be it known that I, EDMUND MORRIS, of the. city of Trenton, in the State of New Jersey, have invented an Improved Chain Pump, of which the following is a full and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The first part of the improvement is in the working part of the pump, by packing the log, so to speak, instead of the bucket.

A, in Figure 1, is a wooden box say two or more feet long, and for an ordinary sized pump about four inches square, made water tight. In this box is inclosed a tube B, Fig. 2, made of pure india rubber, extending from the top down to t-he point O, say about one foot or more. This tube is funnel shaped at each extremity, where also is a flanch or collar D D, by which it is held upright and taut in the box, and secured by rivets passing into blocks which fit tightly in the box at the points mentioned. The inside diameter of the box is about two inches greater than the outside diameter of the tube, so that the tube shall not touch the box except where the former is secured at the top and bottom. Into the space so left vacant the water will descend from the upper part of the log (to be hereafter described) through the openings which will be noticed at the corners of the top block that supports the upper end of the tube, and will occupy the same, thus surro`unding the tube with water. These openings` are made only in the upper block, not in the lower one, which is made perfectly tight. Two sides of the box are extended beyond the point C, and of increased width, to receive the lower pulley over which the chain 'works, and to support the pump when placed in the well. The box, containing tube and pulley, is now ready to be placed in the well. But the box is only two or three feet long, and the well may be twenty feet deep. The box must therefore be spliced by adding to its length; and this additional length may be made in the roughest manner, the only necessary condition being that it shall be tight enough to hold the water as it is raised from the tube until it reaches its outlet above. By using a square box for this purpose, the cheapest possible form will be attained. The splice being made, and the entire log being fixed in an upright position in the well, the wire cord described below is `which they are intended to pass.

adjusted to it over the upper and lower pulleys or reels, as in the ordinary chain pump.

The cord or rope is made of fine annealed wire, extremely flexible, and is supplied with buckets formed of disks of metal, porcelain, or any other suitable material, made perfectly smooth on the edge, and secured to the cord as descril'ied hereafter. They are also made of a diameter somewhat greater than the bore of the rubber tube up They enter the lower end of the tube freely, because the opening is funnel shaped; and an inch or two beyond the opening, where the funnel shape ceases, they begin to bind against the tube. No matter how hard they bind in the buckets, combine to make an air-tight fit;

and to promote this there is added the great pressure on the outside of the tube of the column of water in the log above, which exerts its force through the holes in the corners of the block which supports the upper end of the tube. This pressure causes the tube to hug the bucket with a uniform tightness. Only one bucket is required to act at the same moment, because it escapes from the top of the tube as the next one enters it below; the friction is therefore limited to that generated by a single bucket. The buckets increase or diminish in number according to the length of the tube; and the tube may be made of any material besides india rubber, so that it be equally suitable.

The chain for working in the foregoing liexible tube is constructed as follows, and may be applied to the wooden logs already in use, to much better advantage than the inaccurate link chain with zinc buckets cast thereon.

Fig. 3 represents a disk of metal, porcelain, or other suitable material, having a hole in the center to receive the wire cord, and three or four smaller holes around the central opening, as seen in the drawing. This disk is of porcelain, is made of extra thickness; but if of metal, is turned perfectly smooth on its edge, to prevent its sov chafing against the sides of the tube or pump log, and is placed on its edge in a mold fashioned to produce the desired figure, and the Wire cord A, A, Fig. 4, being passed through the mold and also through the hole in the center of the disk, a hard metal, such as spelter, is poured into the mold in a melted state. This metal envelopes the Wire, and flows through the small perforations around the central hole and becomes a com pact mass, thus forming, in connection with the metal enveloping the wire, a bond of union between the two collars DD, Fig. 5, so strong that the disk is held firmly, on the wire cord. The shape of the casting produced, when disconnected from the disk, is given in Fig. 5, and the complete bucket in Fig 4. As it may be desirable to have these buckets made entirely separate from the cord, when they are to be used in an ordinary wooden log, this is done by so using the mold that the entire shank E, Fig. 5, can be made hollow, with its interior surface grooved or fluted longitudinally or otherwise. In such cases, instead of using a rigid metal like spelter, a flexible or malleable metal, such as tinmans solder, or other suitable alloy, should be substituted, and a fluted mandrel passed through both mold and disk, instead ot' the wire cord. A complete bucket will then be produced with a tubular shank, into which the cord will be introduced to the distance desired, and t-he two tapering eX- tremities of the shank are then by any convenient method violently compressed on to and around the cord. The iuted interior of the shank is thus mashed into the irregularities of the cord, where it will remain firmly in its place. If need be, a rivet may be put in each end of the shank, through the cord, to fix it more securely. The tubular shank, however, may be made of metal not compressible on the cord. But the compressible metal will be found more easily handled and neater, as the mold will deliver the bucket in a finished condition.

Fig. 4, divested of the cord, will represent a tubular shanked bucket thus produced.

The wire cord and the disk, if made of iron, are galvanized to prevent oxidation. The reels or pulleys over which the cord passes, may be made of Wood, having a groove in the face to receive the cord, and indentations for the buckets to Jfall into, as seen in Fig. 1.

I claim- The application of an elastic flexible tube arranged as above set forth, in combination with the box or chamber in which it is inclosed, for the purpose of retaining Water to assist in packing the pump, substantially as described.
